Answer:
745.4K ~ 472.3 C
Explanation:
This is an Ideal Gas Law problem where we have to manipulate the equation a bit. Let's start with the basic:
PV = nRT will be used for both the initial and final, so we will rearrange this problem to state:
(V(initial))/(T(Initial)) = nR/P
Since we know that the pressure, number of moles of He, and ideal gas constant (R) remain the same from start to finish so we can write the problem as such:
(V(initial))/(T(Initial)) = nR/P = (V(final))/(T(final))
or
(V(initial))/(T(Initial)) = (V(final))/(T(final))
Now lets define some of these values:
T(initial) = 25degree (assuming degrees Celsius) ~ 298.15K
V(initial) = 2.0L
V(final) = 5.0L
T(final) = ?
Since we are solving for T(final) let's rearrange the problem once more to be solving for T(final):
T(final) = (V(final)T(Initial))/V(initial)
Now plug in your values:
T(final) = (5.0L*298.15K)/(2.0L) ~ 745.4K ~ 472.3degrees Celsius
The answer I believe would be yes
Do you mean in general or in a piece of paper?
Answer:
Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
Explanation:
Sensation helps us to detect changes in our physical environment.
Sensation occurs in three steps,
- Sensory receptors, these detect stimuli.
- Sensory stimuli are converted into electrical impulses to be decoded by the brain.
- Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.
Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
